To aZZfwzomz't may comem.'

Be it known that I, RosooE V. JEFFERSON, a citizen of the United States, and a resi-l dent. of the' city of Chicago, county of .5 Cook, and State of Illinois, have invented certain new and useful Improvements in vFluid-Fuel Burners, of which the following is a specification.

. Myinvention" relates to a fluid fuel burner, and has for its` object to provide such aV new and improved burner with means for fully distributing the fuel and for supplyin an ample amount of air to said fuel 'an to properly distribute and .atomize said fuel with said air to insure complete combustion thereof.

Other objects will appear hereinafter.

This application is a division ofmy ap.

-plication forl fluid fuel burner and supply apparatus, Serial No. 596,783,1led October Theinvention consists in the combina- .tions and arrangements of parts hereinafter.

described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this Specification, and in which,

Fig. 1 is a burner; and

' Fig. 2 is a vertical sectional view taken on line2-2 of Fig. 1. D

Iny the drawing, I have shownmy improved burner mounted on a fire grate 8 of a furnace, on which the burner may be readily mounted. This burner is of the gravity supply type, and comprises an air distributing member` 9 in the-'form of a vertical cylinder provided atl its lower end with an integral catch pan 10 and a seat Y 11 for rece tionof an air pipeor air conduit 12 which-extends to a suitable opening on the furnace, such as an ash door (not shown), or a suitable opening'lnay be proplan view of my improved .4 5 'vided in the furnace wall, and any suitablev draft control may be provided in said air conduit. A topplateor heating plate 13,

provided with a central cut out or `dished portion 14 and a beveled edge 15, is removabl mounted, as by means of threads, on sai member 9, and e fuel supply pipe or Serial No. 672,705.

feed pipe 16 is threaded on said top plate 13, communicating with the dished portion 14 and extending through member 9 and through the air conduit 12 to a suitable fuel supply. `A curved plate orcap 17 is mounted over lsaid top plate 13 by means of short legs 18 seated in said dished por tion 14, or said cap may be mounted on said top 'plate in any suitable manner so las to provide an annular space 19 of the proper depthl between said cap and plate to suit the particular liquid or /gas used with said burner.A The outer edge 20 of said cap 17 is bent down to directthe fuel downward onto a series or set of annular ring-like members or baiie plates 21, 22 and 23, which have upturned peripheral ianges 2 1 22 and 23', respectively, to retain a small quantity of fuel; and said plates are o,f increased diameter in downward succession, the lower one being of slightly smaller diameter than the catch pan 10. A plurality of series of restricted air openings 25 are provided around member 9, being arranged above each baiiieplate, and` additional air openings 26 are provided around said memberwithin the pan 18 and beneath the lower baille plate, thus providing iair openings above and below each baille plate. Said baie plates are'supported on lugs.27 uand a shoulder 28 formed on member 9, and having openings 29 slightly larger than said lugs to allow convenient removal of said plates. The downwardly bent edge 20 of the cap 17 deiects the fuel '('lownward andparticularly when the top plate 13 is highly heated, and the mixture of fuel and air becomes readily vaporized at the outer and lower edge of the annular .space 19. These baile plates also assist in which fuel intermingles with the air passing at a high velocity through the, restricted air openings 25; but when the fuel is freely supplied in a large quantity, it wlll descend to plate 23 before being fully consumed. The openings 25 above the plates supply a proper amount of air for proper combustion, and if a surplus of fuel should descend over the edge of the lower plate 23, then the openings 26 below said plate 23 will supply sufficient air to insure a proper and full consumption of the fuel to prevent it from reaching the pan l0. It is also to be noted that the air passing out through the air openings moves upwardly and in the proper and natural way enters beneath the liquid fuel descending from the plates, thus passing outwardly and upwardly through the fuel and thoroughly mixing therewith. The combined air openings on member 9 furthermore provide less cross section than the cross section of the air conduit 12, and thus cause the air flowing through said conduit to pass at a higher velocity in its passage through these restricted air openings to mingle with the descending fuel, and thereby said air greatly aids in fully atomizing the fuel and producing a complete fuel mixture descending in the form of a thin, annular film or sheet, producing complete combustion and a maximum of heat from the fuel.

While I have illustrated and described the preferredv lform of construction for carrying my invention into effect this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent, is:

1. A fluid fuel burner comprising an air distributing member, means mounted at the upper part of said member for distributing said fuel in a thin sheet, baffle plates removably mounted on said member above each other, and a plurality of restricted air openings provided around said member for entering air at increased velocity beneath said descending sheet of fuel to admix therewith and vaporize the same.

2. A fluid fuel burner comprising a hollow member, a distributing plate removably mounted on and extending radially beyond The upper end of said member, a fuel conduit leading through said member and olate, a cap mounted over said plate to distribute said fuel downward in a sheet, annular plate shaped members with peripheral flanges mounted around said hollow member and arranged to receive said descending fuel successively, and a series of restricted air openings adjacent each annular member to admit air upward and outward beneath said descendingsheet of fuel. I

A fluid fuel burner comprising ahollow cylindrical member, a distributing plate with a dished portion at the upper part of said member, a fluid conduit leading through said plate to said dished portion, a cap mounted over said plate and curved downward over the edge thereof, annular anges mounted around said member arranged to receive said fuel successively, a plurality of series of air openings around said member adjacent each flange, a catch pan beneath said flanges, and air openings between said pan and the lowermost fiange.
